DTC Descriptor
DTC P0806
- Clutch Pedal Position (CPP) Sensor Circuit Performance




Diagnostic Fault Information






Circuit/System Description

The clutch pedal position (CPP) sensor is an input to the engine control module (ECM). The CPP will be more than 4 volts when the clutch pedal is released and less then 1 volt when the clutch pedal is applied. The CPP is a potentiometer type sensor with the following circuits:

* A 5-volt reference circuit
* A low reference circuit
* A signal circuit



Conditions for Running the DTC

DTCs P0335, P0336, P0502, P0503, P0607, P0808, or P080A are not set.


Conditions for Setting the DTC

The CPP sensor is stuck in range.


Action Taken When the DTC Sets

P0806 is a Type A DTC.


Conditions for Clearing the MIL/DTC

P0806 is a Type A DTC.

Circuit/System Verification

1. Ignition ON, observe the scan tool CPP sensor voltage parameter. The reading should be between 4.75-0.35 volts and change as the clutch pedal is applied and released.
2. Clear the DTCs with the scan tool. Operate the vehicle within the Conditions for Running the DTC, or within the conditions that you observed from the Freeze Frame/Failure Records. This DTC should not set.



Circuit/System Testing

1. Ignition OFF, disconnect the harness connector of the CPP sensor.
2. Ignition ON, observe the scan tool CPP sensor voltage parameter for 0.1 volt.

• If the voltage is within the specified range, replace the CPP sensor.


• If the voltage is not within the specified range, replace the ECM.




Component Testing

1. Ignition OFF, disconnect the harness connector of the CPP sensor.
2. Measure for 1,160-1,175 ohms between the 5-volt reference terminal C and the low reference terminal A of the CPP sensor.

• If the resistance is not within the specified range, replace the CPP sensor.

3. Measure the resistance between the signal terminal B and the low reference terminal A of the CPP sensor. Sweep the CPP sensor through the entire range. The resistance should vary low to high and high to low without any spikes or dropouts.

• If the resistance is erratic with spikes or dropouts, replace the CPP sensor.

4. Apply 5 volts and ground to the applicable terminals of the CPP sensor, and measure the voltage between the signal terminal B and the low reference terminal A. Sweep the CPP sensor through the entire range. The voltage should vary between 4.3-0.6 volts without any spikes or dropouts.

• If the voltage is not within the specified range or is erratic, replace the CPP sensor.




Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.

* Clutch Pedal Position Sensor Replacement (Service and Repair)
* Control Module References (Programming and Relearning) for ECM replacement, setup and programming.
